Solo, you're talking about -two highs- able to pump out 4k damage. That's sufficient to force an utterly stupid choice. If I close in, tackle, they suddenly RLML me, I've got zero good options in a T1 hull. If I pull range to GTFO, transversal drops, suddenly all the rest of their highs can hit me. If I stick around for the reload, I'm deep in hull and have no shields when the next volley comes around, and I die. My only viable option is not engaging anything sporting RLML turret models. Ever. And this is assuming they're not fitting a web. Rupture with a web and two RLMLs? Death unto frigates.
I like the general thinking of high DPS + long reloads as an interesting way to distinguish the RLML, but you don't need to be crippling the frigate ecosystem right as it's starting to bounce back.
